Question 200824: x^2 + x + sqrt x^2 + x – 2 = 0
Answer by RAY100(1637)   (Show Source):
You can put this solution on YOUR website! x^2 +x +sqrtx^2 +x -2 = 0
.
x^2 +x+x+x-2=0
.
x^2 +3x -2=0
.
use Quadratic Formula
.
a=1,,,,b= 3,,,,c=-2
.
x=[ -(3) +/- sqrt { (3)^2 -4 (1) (-2) } ] / 2(1)
.
x= [ -3 +/- sqrt { 9 +8 } ] /2
.
x= [-3 +/- 4.123 ] /2
.
x= .5615,,, -3.562
.
check by subst into original, with calc,,,,ok
